Apple watch requiring password to pair

My daughter has had an apple watch SE for about a year. She received a iPhone 14 for Christmas and I am trying to pair her watch to the new phone. It is requiring a password, which apparently cannot remember. I have successfully reset her Apple ID Password, which the watch pairing procedure will not accept. I then tried to remove the watch as one of her devices in Apple ID, as the instructions suggested, but it is still requiring a password. Any suggestions on how to get the watch paired to her phone would be appreciated.

Thanks!
